You bought a ColorHug!

First, thanks. I really appreciate you giving Open Hardware a try. Second, please join the colorhug-users group and tell us what you think. All announcements about new firmware updates and new client code will also be done on the mailing list.

Check the hardware

First, we check the hardware can be accessed. Insert the LiveCD and reboot, making sure you boot the CD when the BIOS screen shows. Then, connect the ColorHug and run:

$ colorhug-cmd set-leds green 5 200 200

This should flash the green LED 5 times.

Get latest firmware

$ /usr/bin/colorhug-flash
flash program

Get up to date calibration matrices

$ /usr/bin/colorhug-ccmx
ccmx program

Then click Refresh and select calibration matrices for each display type that match your display kind (using the default calibration is usually good enough for most people).

Measuring a test patch

$ /usr/bin/gcm-picker

Hold the device against the screen and click the Measure button. Hopefully the color on the screen will roughtly match the sample color.

Then we can create a ICC profile.

$ /usr/bin/gnome-control-center color

Good luck!
